This is pretty much exactly my feeling. I've found for myself that concentrating on keeping my head in place isn't enough though. I try to feel like the whole line from the crown of my head to my tail bone isn't moving right or left at all. Obviously this isn't really true, since I'm tucking my hips and with the coil on the backswing it's not actually physically possible for no single vertebrae to move left or right, but thinking of that feeling helps me. Also, concentrating on a VERY quiet lower body helps me too.
I've found that I hit the ball much more consistently when I err on the side of almost not moving or twisting my lower body at all and getting all the rotation from the back (lower and upper) and shoulders, rather than erring the other way. I know it's not what most would recommend, but I've found it works for me, and it helps me keep my swing more compact, and actually helps me get maximum coil in my core without going all John Daly on the backswing length, which gives me a little extra power too.
